I assume you mean port 8 on the relay shield, as there is no port 9.
you would have to add:
Code:
ROSolenoid solenoid(9);
before your enabled() function. The 9 is because Robot-Open 0-indexs ports.
you would also need to add:
Code:
if (usb1.btnA())
solenoid.on();
else
solenoid.off();
inside the enabled() function.
This would cause the solenoid to mimic the button presses.
However I cannot test this code as I do not have the hardware myself.
also is it necessary for the burst to be 1 second?
